NON-CORRQSIVE -ME'I ALLIC ALLOY.

N6 Drawing; i

To allwhbm it may concern Be it' known that I, J 019m Cour, a citizen of the United States :residing at -Mari-on, in the county of ari-(mane State of'Ohio,

have invented certain new and useful Im-' provement s in Non-Corrosive -Metallic Alloys, of which the following is a specification.

This invent-ion relates. to an improved nietal alloy and has for its primary object to provide a composition consisting of a number of mineral constituents homogeneously commmgled or mixed with a suitable deoxidizing agent whereby a metal alloy is produced which Zmay be utilized as a sub 'stitute for nickel-plating and may be commercially used in the manufacture of various articles.

Another object of'the invention is to produce a metal alloy which has great strength and durability, may be inexpensively compounded and is particularly desirable and serviceable in the manufacture ,of piano strings, bells and similar articles wherein it is'e'ssential that the metal be 'noncorrosive in order to preserve the tone qualities thereof.

With the above and other objects inview as will become apparent as the description proceeds, the invention consists in. the com bination of the several mineral ingredients hereinafter specified, mixed and treated in the manner set forth.
